Setting option bytes failed #7

Open FLESHDESTROYER opened 1 month ago

FLESHDESTROYER commented 1 month ago

I just assembled my os3m mouse and was able to get the firmware flashed. Continuing with the steps, I unchecked BOOT_SEL and clicked apply but it failed to program. Now I CANT connect the board back to the programmer, is there anything I can do?

I got enough components to make 2 PCBs and the same thing happened to the second one.

It’s not clear to me what you did, exactly? I tested the instructions as written and had no issues. Do you have an ST-link you can use to read the option bytes?

FLESHDESTROYER commented 1 month ago

I followed your instructions exactly and everything was working fine. I got the firmware downloaded and it all looked good but then when I applied the option bytes, I think it said it timed out and disconnected and failed. Now I can't get it to show up in device manager or connect to the programmer. I tried shorting the pins and it worked for like a second but then disappeared again. This is all through usb. I just ordered an st link (not exactly sure if it's the right one). If you're willing to help further troubleshoot you can add me on discord @fleshdestroyer if it makes communication easier. Thank you.

Without any further debugging info, it sounds like you fell into the common pitfall of resetting the board or otherwise disconnecting before you set the option bytes. Once you flash the firmware, it is critical that you immediately change the option bytes, or else you get the issue as mentioned at the end of step 3. Not much else can be done besides getting an st-link at that point.

FLESHDESTROYER commented 1 month ago

Both times I immediately went to set option bytes without disconnecting or resetting the board. I just followed the steps but it wasn't able to apply the option bytes. I'm pretty sure it timed out from trying to apply it and just disconnected it. I just got a V2 ST-LINK and I'm getting the message "UR connection mode is defined with the HWrst reset mode".

I believe this is referring to updating the actual STlink, not the OS3M mouse. I would update the firmware then see if you can connect to the mouse using STlink

FLESHDESTROYER commented 1 month ago

I think the firmware is up to date for the st-link, it also seems to fail when I try to upgrade it anyway. "St link device lost when exiting upgrade mode". It still won't connect to the board saying the same HWrst reset mode. I just want this to work 😩 20240719_194147

Do you have any other suggestions or advice? Could it be assembled incorrectly? I don't know why it didn't work over usb

Unfortunately I bought that ST-link also and it doesn't work with Cube Programmer. It just works with ST-link utility but that can't open .Elf files. I had to buy the less bootleg version. Try to return the one you bought and check the end of this thread to see how I bought the correct ST-link: https://github.com/spoter368/os3m-firmware/issues/4

Thank you so much for the help! I did cheap out on this one assuming they were the same haha. I will return this one and try another... Can you tell if this one will work? https://www.amazon.com/gp/product/B07SQV6VLZ/ref=ox_sc_act_title_12?smid=A30QSGOJR8LMXA&psc=1

That one won't, two 2022 reviews say it doesn't work with Cube programmer (shows up as single digit serial #). It's best to manually look through reviews, if you search "Cube" in the reviews it doesn't show all reviews that mention cube lol. image

The better seller ("Aideepen") I bought from on the Amazon(dot)ca also sells on amazon(dot)com... however on (dot)com they have more mixed reviews; some saying it does work, some saying it doesn't. That's better than other sellers so I suggest buying from this link despite the gamble. Return it and sue me if I'm wrong: https://www.amazon.com/Aideepen-ST-Link-Programming-Emulator-Downloader/dp/B01J7N3RE6

Thank you, in glad I double checked. I ordered this one and hopefully it will connect.

The new ST LINK worked, thank you. Seems like everything worked as per the instructions but I tried to test the game controller to see if the axes would move but they don't seem to be doing so.

FLESHDESTROYER commented 1 month ago

@spoter368 The new ST LINK worked and I followed your steps exactly but when testing with the game controller, nothing happens. I confirmed by pcb layout with @hotsgit and I even copied his firmware file and it still downloads properly but thats about it. This is what I saw on my pc image this is what I saw on my laptop after using his firmware image

spoter368 commented 1 month ago

Hard to say what’s wrong. The firmware works for myself and several others who have tested the board.

I want to comment more broadly on the project, to any others who are thinking about making one of these: this is not meant to be a product, this is meant to be a project. There is a requisite level of hardware, firmware, and software skills it will take to get it working. I have lowered the barrier to entry substantially by providing a known working set of hardware, firmware, and software on my machine. To get it working on your machine may require additional knowledge or setup. I will not be providing support for this project unless you provide clear evidence that something I have provided is broken or not functioning. Thank you and best of luck.
